In this study, the hydrochemical characteristics of groundwater were assessed based on 64 shallow samples collected in Guanzhong Basin, China, and health risk nitrate (NO3-) drinking water was assessed. addition, spatial distributions major quality indicators investigated, while bivariate plots, saturation index, stable isotopes used to reveal processes controlling hydrogeochemistry. The results showed that study area mostly fresh water. However, maximum average NO3– concentrations 397.0 92.9 mg/L, respectively, indicating serious pollution. percolation contaminated river exhibited considerable impacts quality. Carbonate dissolution process groundwater, human activities responsible for high pollutants, especially NO3–. Evaporation fraction revealed by hydrogen oxygen ranged from 4 13% 11%, respectively. High non-carcinogenic risks adults children observed about 46.88 75% samples, value ranges 0-6.00 0-14.06, with values 1.36 3.19, children,

Assessment of coastal river water quality in Bangladesh: Implications for drinking and irrigation purposes

PLoS ONE, Год журнала: 2024, Номер 19(4), С. e0300878 - e0300878

Saltwater intrusion in the coastal areas of Bangladesh is a prevalent phenomenon. However, it not conducive to activities such as irrigation, navigation, fish spawning and shelter, industrial usage. The present study analyzed 45 water samples collected from 15 locations during three seasons: monsoon, pre-monsoon, post-monsoon. aim was comprehend seasonal variation physicochemical parameters, including temperature, pH, electrical conductivity (EC), salinity, total dissolved solids (TDS), hardness, concentrations Na+, K+, Mg2+, Ca2+, Fe2+, HCO3-, PO43-, SO42-, Cl-. Additionally, parameters essential for agriculture, soluble sodium percentage (SSP), absorption ratio (SAR), magnesium (MAR), residual carbonate (RSC), Kelly's (KR), permeability index (PI), were examined. Their respective values found be 63%, 16.83 mg/L, 34.92 145.44 1.28 89.29%. integrated quality determined using entropy theory principal component analysis (PCA). resulting (EWQI) SAR 49.56% respectively, indicated that are suitable drinking but unsuitable irrigation. These findings can assist policymakers implementing Deltaplan-2100, focusing on sustainable land management, cultivation, agricultural production, environmental preservation, resource protection deltaic Bangladesh. This research contributes deeper understanding variations hydrochemistry rivers, aiding comprehension salinity origins, mechanisms, causes.
